INTERNATIONAL CERTIFICATES
In order to prevent the spread of infectious diseases,
certain countries require that visitors should be vaccinated
or inoculated against specific diseases.
International certificates have been prescribed for smallpox,
cholera and yellow fever. When completed by a medical practitioner,
the certificate must be authenticated by the Medical Officer of
Health.
During the year, 11,882 of these certificates were
authenticated. In addition, 9 special certificates were issued
to travellers who refused vaccination on medical or religious
grounds.
